Digital electrohydraulic servoactuators are
stand-alone units performing closed loop
position controls.
The complete motion control cycle can be
operated by external signals (from
machine PLC) or programmed internally
to the controller.
S options add alternate pressure / force
control to the basic position one with
pressure transducers or load cell factory
pre-assembled and wired.
The servoacuators are composed by a
servocylinder with position transducer,
servoproportional valve with integral
driver + axis controller, factory assembled
and tested.
They can be provided with optional
fieldbus interfaces for functional
parameters setting, reference signals and
real time diagnostics.
The USB interface is always present for
connection to Atos PC software which
allows to easily customize the AZC
configuration to the specific application
requirements.

2MAIN CHARACTERISTICS
4ALTERNATED P/Q CONTROLS
Assembly position Any position
Ambient temperature range standard execution = -20°C ÷ +60°C
Storage temperature range Standard execution = -20°C ÷ +70°C
Protection degree to EN60529 IP66 / IP67
Duty factor Continuous rating (ED=100%)
S options add the closed loop control of pressure (SP) or force (SF and SL) to the position control function. A dedicated algorithm alternates
pressure (force) depending on the actual hydraulic system conditions.
For detailed information about SP, SF, SL controls, see tech table GS002.
Digital servoproportionals direct or pilot operated include integral valve’s driver + axis controller to perform the position closed loop of hydraulic
actuator. Axis controllers are operated by an external or internally generated reference position signal.
For detailed information about integral axis controller see tech table FS230.

Fieldbus allows the direct communication of the servoactuator with machine control unit for digital reference signal, diagnostics and settings
of functional parameters. Analog reference signal remain available on the main connector for quick commissioning and maintenance.
For detailed information about fieldbus features and specification see tech table GS510.

6 ACTUATOR’S TRANSDUCER CHARACTERISTICS
6.1 Position transducers
The accuracy of the position control is strongly dependent to the selected position transducer. Four different transducer interfaces are
available on the controllers, depending to the system requirements: potentiometer or analog signal (A execution), SSI or Encoder (D exe-
cution). Transducers with digital interface allow high resolution and accurate measures, that combined with fieldbus communication grants
highest performances. Transducers with analog interface grant simple and cost effective solutions.
6.2 Pressure/force transducers
The accuracy of the pressure/force control is strongly dependent to the selected pressure/force transducer. Alternated pressure/force
controls require to install pressure transducers or load cell to measure the actual pressure/force values.
Pressure transducers allow easy system integration and cost effective solution for both alternated position/pressure and position/force
controls (see tech table GS465 for pressure transducers details).
Load cell transducers allow the user to get high accuracy and precise
regulations for alternated position/force control.
The characteristics of the remote pressure/force transducers must be always selected to match the application requirements and to
obtain the best performances: transducer nominal range should be at least 115%÷120% of the maximum regulated pressure/force.
